The review focuses on recent progress in the breeding of small grain cereals (barley, wheat, oats) for resistance to the barley yellow dwarf virus (BYDV). First, the symptomatology of barley yellow dwarf (BYD) disease is briefly described and the genome of BYDV, its serotypes and mechanisms of its replication and translation in host plants are characterized. Great attention is paid to the description of resistance genes and sources of BYDV resistance that are currently used in some breeding programmes of barley, wheat and oats. In barley, the introduction of the Ryd2 gene into high-yielding cultivars is still desirable. An example of recent...

Crop yields are reduced by 70-80% due to a water stress situation specifically during the reproductive stage and are not able to fulfil the needs of food requirement in developed and developing countries of the world. Earlier work was mainly focused on the use of morphological or physiological and molecular aspects for improved stress tolerance. Efforts are being made to overcome this problem with the help of today's sophisticated and advanced technology through genomics, proteomics and metabolomics. The presented model summarizes our work in the last five years to mine anatomical parameters as a novel approach to further improving introgression or...

Several sets of wheat inter-varietal chromosome substitution lines (SLs) have been produced over the last fifty years at the CRI (formerly RICP) in Prague-Ruzyně, based on cytogenetic manipulations using aneuploids. Lines with defined genes have been obtained which significantly influence growth habit and flowering time and these have been used particularly in the study of the genetics and physiology of flowering. The sets of lines include substitutions of homoeologous group 5 chromosomes carrying Vrn genes that control vernalisation response, homoeologous group 2 chromosomes with Ppd genes controlling photoperiodic sensitivity, and...
Chromosome doubling effects of selected antimitotic agents in Brassica napus microspore cultureOriginal Paper

Effects of microspore culture treatment with antimitotic agents colchicine, trifluralin and oryzalin on the frequency of embryo formation, embryo development, plant regeneration and diploidization rate in three F1 hybrids of winter rapeseed cultivars were compared. The ploidy level analysis of 1709 flowering microspore-derived plants showed that in vitro applications of all antimitotic drugs increased the rate of doubled haploid (DH) plants significantly. The mean rate of DH plants from the trifluralin treatment was 85.7%, from colchicine 74.1% and 66.5% in the case of oryzalin, while only 42.3% in the untreated control variant...
